ABSTRACT
Objective To study the teaching innovation of the scientific experiment exploration course in biomedical engineering specialty based on its characteristics involving in animal physiological parameters acquisition, circuit system design, signal processing and etc. Methods The course aimed to guide the student in observation learning, practice and inquiry with considerations on course significance,basic principles for designing the course,implementation scheme of course teaching, suggestions for course improvement, instances of practical teaching and etc. Results Four basic principles were proposed for course teaching. An implementation scheme was determined with emphases on teaching materials, theory, practice, discussion and exploration. The course had the rule being inquiry, and some suggestions were put forward about student feedback, scientific research progress, experiment platform renewal and etc. Conclusion Teaching practice proves that the improved course contributes to enhancing the student's understanding of experiment exploration of biomedical engineering specialty and to promoting multi-discipline fusion and cross-over personnel training, and thus is of great reference for other universities.
ABSTRACT
Amyloidosis is less involved in the respiratory tract. The tracheobronchial amyloidosis is rare, and the amyloid changes involved in the larynx, trachea and bronchus are more rare. The study introduces a case of the primary laryngeal and tracheobronchial amyloidosis. The patient was diagnosed as primary laryngeal amyloidosis, and had tracheobronchial amyloidosis after 15 years. Due to the rare and non-specific clinical manifestations of the disease, the patient was misdiagnosed as upper respiratory tract infection and bronchial asthma.After the treatment of the clamp of the bronchoscope and argon knife,the symptoms were significantly relieved in the patient.At present,the disease is stable and has not relapsed,but it still needs to track the long-term prognosis.
